Description

The invention relates to a direct plug-in device for direct plugging onto a printed circuit board.

It is known an arrangement for the electrical and mechanical connection of plug-in elements via a socket with a printed circuit board, which is designed for high electrical and mechanical requirements.

There are also known connection arrangements for printed circuit boards, which allows a direct insertion of a male part on a circuit board without attached to the circuit board socket.

WO 2010/063459 the same applicant discloses a connection arrangement with a plug-in element having at least one contact element, in particular a plurality of plug-in contact elements, as well as with a printed circuit board with plated through holes, which are arranged in an arrangement corresponding to the arrangement of the contact element or the contact elements of the plug element, wherein the Holes and the plug-in contact element or in them plug-in contact elements are coordinated so that connect the plug element by hand by inserting the contact element or the contact elements in the holes with the circuit board and remove it by hand, the connection assembly with a vibration robust mechanical protection against unintentional removal of the plug element is provided by the circuit board. The contact element or the contact elements may or may optionally be configured as a spring-like contact element or spring-like contact elements with a reversible deflection characteristic.

Although such a connector assembly has many advantages, dealing with the relatively sensitive contact elements as well as its correct positioning on the circuit board can be challenging for a user.

The invention is based on the object to provide a direct plug-in device for direct plugging onto a printed circuit board, which is robust and easy to handle for a user.

To achieve this object, the invention proposes a direct plug-in device, a connection arrangement, a vehicle, a method and a use with the features mentioned in the independent claims. Further developments of the invention are the subject of dependent claims.

According to one exemplary embodiment of the invention, a direct plug-in device for direct plugging onto a printed circuit board is provided, wherein the direct plug-in device has a plug-in element which has a receiving housing and a plurality of plug-in (for example spring-like) contact elements received thereon. The direct plug-in device further has a plug element receptacle which is arranged for at least partially (in particular circumferentially continuous) receiving the plug element such that in the accommodated state of the plug element, the plug element receptacle laterally covers the contact elements at least partially (in particular fully). The plug-in element receptacle has at least one pre-adjustment structure arranged on the printed circuit board side, which can be connected to the printed circuit board by fitting the plug element receptacle to at least one corresponding pre-alignment structure of the printed circuit board in such a way that the contact elements are aligned with correspondingly formed contact element openings of the printed circuit board in the connected state. The plug element can be moved relative to the preassembled on the printed circuit board plug-in element receptacle so (in particular pressed, pushed or rotatable) that thereby the contact elements from the plug receptacle extendable and insertable into the correspondingly formed contact element openings.

According to another embodiment of the invention, there is provided a connection assembly comprising a printed circuit board having at least one pre-alignment structure and a plurality of contact element openings, and a direct plug-in device having the features described above. The direct plug-in device is for direct plugging onto the printed circuit board by connecting the at least one Vorjustierstruktur the plug element receptacle with the at least one corresponding Vorjustierstruktur the circuit board and by means of subsequent movement of the plug element with respect to the pre-aligned on the circuit board. Plug element receptacle furnished. As a result, the plurality of contact elements can be moved out of the plug-in element receptacle and inserted into the plurality of contact element openings.

In accordance with yet another embodiment of the invention, a vehicle (eg, a motor vehicle, a passenger car, a truck, a bus, an agricultural vehicle, a baler, a combine, a self-propelled sprayer, a road construction machine, a tractor, an aircraft, an aircraft, a helicopter, a spaceship, a zeppelin, a watercraft, a ship, a rail vehicle or a track), which has a connection arrangement with the features described above or a direct plug-in device with the features described above.

According to a further exemplary embodiment of the invention, a method is provided for directly plugging a direct plug-in device onto a printed circuit board, wherein in the method a plug-in element is provided which has a receiving housing and a plurality of pluggable contact elements received thereon. The plug-in element is at least partially accommodated in a plug-in element receptacle in such a way that in the accommodated state of the plug-in element the plug element receptacle laterally covers the contact elements at least partially. The plug-in element receptacle is placed on the printed circuit board for connecting at least one pre-adjusting structure of the plug element receptacle arranged on the side of the printed circuit board with at least one corresponding pre-alignment structure of the printed circuit board such that in the connected state the contact elements are aligned to form corresponding contact element openings of the printed circuit board. The plug-in element is moved in such a way in relation to the pre-adjusted plug-on element receptacle mounted on the printed circuit board in such a way that the contact elements are thereby extended out of the plug-in element receptacle and introduced into the correspondingly formed contact element openings.

According to another embodiment of the invention, a connection arrangement with the features described above for transmitting an electric current of at least 5 amperes, in particular of at least 10 amps, more particularly of at least 20 amps, is used between a contact element of the direct plug device and the circuit board attached thereto.

According to an exemplary embodiment, a hand-pluggable and manually detachable system is provided, with a faulty electrical contact between sensitive contact elements on the one hand and a printed circuit board on the other hand is made possible by a plug-in element with the example, spring-like contact elements received and surrounded by a skirt-like plug element receptacle is. This makes it possible that the plug element receptacle in the connected state with the plug element preserves the contact elements against unwanted mechanical damage. Slidably provided with respect to the plug element, the plug element receptacle is configured such that an end region of the plug element receptacle can be provided with one or preferably a plurality of pre-alignment structures, which enable a correct arrangement of the direct plug device on the circuit board. For this purpose, it must be ensured that the one or more pre-adjustment structures of the plug element receptacle is arranged on the one or more corresponding pre-adjustment structures of the printed circuit boards. For example, the Vorjustierstrukturen can be engaged with each other, so that a correct positioning between the direct plug device and circuit board is ensured even before the actual plugging operation. A mere further pressing or screwing the plug element into the plug element receptacle by a user is then sufficient to move the plug element to the circuit board, wherein the circuit board and plug element receptacle can remain unchanged during this movement relative to each other. As a result of the movement, the sensitive contact elements from the direct plug-in device are also extended on a printed circuit board-side end and immersed in the contact element openings of the printed circuit board already arranged at the correct position on the basis of the pre-adjustment. Thus, the actual connection and electrical contact can be achieved with an intuitive and simple handling, with a misalignment can be reliably excluded. Also, the provision of a socket on the circuit board is unnecessary, since the electrical contact can be achieved directly between the contact elements and a providable in the contact element openings electrically conductive contacting of the circuit boards. By this measure, a protection of the sensitive contacts is simultaneously made possible from damage and realized a pre-adjustment between direct plug-in device on the one hand and printed circuit board on the other.

In addition, additional embodiments of the direct plug-in device will be described. These also apply to the connection arrangement, the vehicle, the method and the use.

Generally, in the context of this application, a pre-adjustment structure can be understood as any feature (physical structure, recess, color marking, magnetic elements, etc.) on the plug element receptacle or printed circuit board, which promotes a corresponding arrangement to a feature of the respectively different pre-adjustment structure. According to a preferred embodiment, the at least one pre-adjustment structure of the plug element receptacle can have at least one pre-alignment pin (that is to say a projection). The at least one corresponding Vorjustierstruktur the circuit board may have at least one Vorjustieröffnung (for example, a through or blind hole). In particular, the Vorjustierstruktur a pin and the corresponding Vorjustierstruktur be a corresponding Vorjustieröffnung in the circuit board, so that then a positive engagement of the Vorjustieröffnung is made possible by the Vorjustierzapfen. It is also possible to provide a Vorjustierzapfen on the circuit board and to provide the Steckelementaufnahme with a Vorjustieröffnung. However, it is preferred to provide a plurality of Vorjustierzapfen on the plug element receptacle and corresponding Vorjustieröffnungen on the printed circuit board, as a correct positioning for a user is particularly intuitive given and the circuit board can be made flat and mounted.

According to one embodiment, in the accommodated state of the plug element (in the plug element receptacle) and before moving the plug element receptacle the contact elements on the circuit board side protrude. By this measure, the contact elements not only laterally (laterally), but also the underside (circuit board side relative to the mounted state) are mechanically protected, as long as the direct plug assembly is not inserted into the circuit board. In this position, the direct plug-in device (for example by means of a spring) may be biased. Only by the user made relative movements of plug-in element to the plug element receptacle are clearly extended, the contact elements and then in turn protrude a printed circuit board-side end of the plug element receptacle to be received there in the contact element openings and possibly jammed.

According to one embodiment, the plug-in element can have at least one latching structure, which is set up for latching the plug-in element with a corresponding latching opening in the printed circuit board. According to one embodiment, a latching mechanism or, more generally, a mechanical latching mechanism may be provided by the plug-in device. According to another embodiment, such a latching mechanism (realized, for example, as a barb or by other means) may be provided on the circuit board side. According to the invention can be saved due to the elimination of a socket and a resulting direct connection between the circuit board and plug material, eliminating an electrical interface and thus a better quality at lower cost can be achieved. In particular, electrical components, such as harnesses, can be flanged directly to the circuit board. Overall, with the connection arrangement, a current strength of, for example, 70 to 100 amperes, in particular up to 150 amps and more, can be achieved. For example, a current load of 10 to 15 amperes can be carried per contact element, for example via a battery feed.

The latching structure can be set up for vibration-robust latching of the plug-in element with the printed circuit board. The term "vibration-resistant mechanical fuse" may in particular have the meaning that, even in the presence of vibrations acting on a technical system having the connection arrangement, unintentional detachment of the plug-in element from the printed circuit board is avoided. In particular, vibrations, such as occur in a motor-driven, in particular combustion engine driven device (in particular vehicle), lead in a vibration robust mechanical fuse configured to no adverse effect on the system function. In particular, when installing the connection assembly in the engine compartment of an off-road vehicle, the vibrations normally occurring there should not lead to an undesirable loss of electrical contact between the contact elements and the mating contact in the respectively associated bore of the circuit board. Thus, in order to achieve the vibration robustness, the mechanical protection with respect to material, dimensions, fastening forces, etc., be designed so that the corresponding vibrations do not lead to any unwanted detachment of the plug-in element from the circuit board. The connection arrangement may be for realizing the vibration robustness in accordance with Industry standard ISO TS 16750 , especially ISO TS 16750-3 be designed. ISO 16750 defines a standard for mechanical load requirements for off-road vehicles. In order to achieve the vibration robustness, the connection arrangement may be further designed, the Standard IEC 60512-4 fulfill, in particular at least one of the sub-requirements IEC 68.2.6 (vibration sinusoidal), IEC 68-2-27 and IEC 68-2-29 (multiple shocking), IEC 68-2-64 (broadband noise), IEC 68-2-64 (vibration in a cold atmosphere) and IEC 68-2-50 and IEC 68-2-51 to fulfill (vibration in a warm atmosphere).

With such a latching element unintentional removal of the plug-in element from the printed circuit board can be avoided. The term "unintentional removal of the plug element from the printed circuit board" may in particular have the meaning that the fuse reliably avoids an unwanted removal of the plug element by a user. However, this term is also intended to express that an undesired loosening of the connection by motor-induced vibrations or the like is avoided. The term "peeling off" therefore includes, in particular, an active pulling and a release due to external influences without the involvement of a user. The mechanical securing of the plug element and the printed circuit board can with a mechanical load capacity according to ISO 16750-3 (especially in the version ISO 16750-3: 2007 ) get connected. In other words, the design of the mechanical fuse may be such that a correspondingly configured connection arrangement will perform the tests described in U.S. Pat ISO 16750 , especially in ISO 16750-3 (as defined on the priority date of this patent application) can be successfully completed. For example, the mechanical fuse may include the male and the printed circuit board with a mechanical fastening force of at least about 100 Newton, in particular at least about 200 Newton, more particularly at least about 300 Newton connect. Such fastening forces may be sufficient to allow sufficient vibration resistance.

According to one embodiment, at least one latching structure may be formed on at least one of the plurality of contact elements. According to one embodiment, the latching structure can thus be designed directly on the contact elements, that is to say in one piece with them. This allows the compact production of direct plug-in device with low cost. Alternatively or additionally, at least one latching structure may be formed separately from the plurality of contact elements. In such an embodiment, the electrical contact and the mechanical attachment can be optimized separately.

According to one embodiment, the plug element and the. Plug element receptacle be formed such that, starting from a state in which the contact elements are inserted into the correspondingly formed contact element openings, the plug element of the circuit board so separable (especially peelable by hand) that moves back automatically in the separation of the plug element with respect to the plug element receptacle , so that the plug element receptacle again laterally covers the contact elements. This embodiment shows that the movement mechanism between the plug-in element and the plug-in element receptacle can be configured such that when the direct plug arrangement is removed from the printed circuit board, the kinematics performed during the insertion process are inverted, so that the contact elements can be moved back into the interior of the plug element receptacle and thus reliably against mechanical damage Destruction can be protected.

According to one embodiment, at least one circumferential portion of a printed circuit board-side edge of the plug element receptacle may have a flexible lip. Such a flexible lip can be configured, for example, as a continuous rubber ball or as a cushioning foam body which can act as a damping or pretensioning mechanism when the plug-in element holder is placed on a surface of the printed circuit board. If the plug element is moved further in the direction of the printed circuit board after the lip has been fitted, then the flexible lip counteracts a counterforce, which promotes correct alignment. In addition, a user receives a haptic feedback that now the actual electrical contacting process begins.

According to one embodiment, the plug element receptacle may have a clamping strap for clamping the plug element to the plug element receptacle. Such a clamp allows the separately manufactured components of plug-in element on the one hand and plug receptacle on the other hand to secure each other securely, while allowing the required relative movement.

According to one embodiment, the plug element receptacle may have a first sleeve and a second sleeve which can be received or received rotatably in the first sleeve. The second sleeve can have an internal thread and the plug element can have a corresponding external thread or at least one corresponding pin (for example a bayonet pin) for engagement in the internal thread, so that the plug element can be screwed into the second sleeve by turning the second sleeve, with which the contact elements be introduced into the correspondingly formed contact element openings. During screwing in, the second sleeve can rotate while the first sleeve remains stationary and the plug element performs a rotationally free longitudinal movement, d. H. is linearly shifted. Such a configuration is particularly preferred in so-called round plugs. The two sleeves can then be designed substantially hollow cylindrical. First, the second sleeve is inserted into the first sleeve, for example, rotatably locked in this. In the latched state, the second sleeve is still rotatable together with its internal thread relative to the first sleeve. In this embodiment, the external thread or at least one corresponding pin of the plug element is screwed to the internal thread of the second sleeve. This is achieved particularly advantageously by non-rotatable holding of the plug element and simultaneous rotation of the second sleeve accommodated in the first sleeve. As a result, it is possible that the plug element with its contact elements in the result is moved in a straight line similar to a plug movement on the circuit board to immerse in the contact holes of the circuit board, whereas the second sleeve accomplishes the required rotational movement for screwing. Alternatively, it is also possible to provide an external thread on the second sleeve instead of an internal thread at least one bayonet pin and on the plug element instead of the bayonet pin.

According to another embodiment, in the direct plug-in device, the first sleeve may have a support portion (eg, a support shoulder) for supporting a support structure (eg, a support ring) of the plug member. The second sleeve and the plug element can corresponding linear guide means (for example, at least one guide lug on the plug element and at least one corresponding guide groove on the second sleeve, or vice versa), which prevent a relative rotational movement between the second sleeve and the plug-in element. The first sleeve can have a knurl (that is to say a rotatable grip piece), so that the support section can be lowered by means of rotation on the knurl, whereby the plug element can be lowered and thereby performs a rotationally free longitudinal movement, whereby the contact elements are inserted into the correspondingly formed contact element openings. Such a configuration is comfortable and error-robust operation, see. for example 14 to 16 ,

According to one embodiment, the plug-in element receptacle can be formed from an electrically insulating material, in particular from plastic. In this embodiment, the plug element receptacle can also be used as electrical protection, as this unwanted electrical contact between a user and attached to the plug element contact elements is prevented by electrically insulating the plug element receptacle.

According to one embodiment, the direct plug-in device may have at least one relay and / or at least one fuse. Relay or fuse can be electrically coupled to the plug-in contact elements. Thus, for example, a relay or a fuse may be provided in the plug-in element, so that a direct plug-in is also possible for such or other electronic components.

According to one embodiment, the circuit board socket-free, thus flat, be formed. By providing the circuit board without separate sockets for insertion of a plug assembly, the structure of the circuit board is compact and simple. At the same time a direct connection between the direct plug-in device according to an embodiment of the invention and the circuit board is made possible.

The contact elements can be high current capable. The term "high-current-capable contact elements" may in particular have the meaning that the contact elements are designed with regard to dimension, material, mutual spacing, etc. in such a way that they are suitable for carrying a high electrical current. In other words, when using high-current-capable contact elements, an electric current in the ampere range can be transmitted from the contact elements to the conductor tracks of the printed circuit board. A high current can be used in particular if the contact elements are specially designed to be able to transport at least 5 amperes per contact element, in particular at least 10 amperes per contact element, without jeopardizing the intended use of the connection arrangement. In other words, the contact elements should be designed in a high-current configuration so that an undesirable heating of the connection arrangement is avoided or any other technical function of the connection arrangement suffers damage, when such high currents are conducted by means of the contact elements. In particular, the high-current-resistant design of the contact elements can be designed so that the contact elements together can carry cumulative currents of at least 50 amperes, in particular of at least 100 amperes. The high current capability of the contact elements can be considered as given when the contact elements are connected to a vehicle battery and can deliver power from the vehicle battery to the connected circuit board trouble-free. In particular, the high current capability can be considered as given when contact resistance according to the Einpressnorm the requirements of IEC 60512-2 fulfill.

The holes and the plug-in contact elements can be an electrical load capacity according to ISO 16750-2 (in the version valid on the priority date of the present patent application). The holes and the plug-in contact elements can in particular an electrical load capacity according to ISO 16750-2 in the version ISO 16750-2: 2006 to have. In other words, the contact elements can be configured mechanically and electrotechnically in such a way that the electrical load tests according to the named industrial standard are successfully completed.

In particular, each of the plug-in contact elements can be designed for an electrical load capacity of at least about 5 amperes, in particular of at least about 10 amps, more particularly of at least about 20 amps. By providing a plurality of pins (which can be operated separately from one another electrically), a total current carrying capacity of, for example, 70 amps and more can thus be achieved.

The plug-in element can be inserted by hand into the printed circuit board or pulled out of it. Under a Einsteckbarkeit or removability of the plug element "by hand" may be understood in the context of this description in particular that the insertion and removal forces even with provision of a plurality of contact elements, for example at least five contact elements (in particular at least ten contact elements) are sufficiently low that they can be applied by the muscular strength of an average adult human user.

Each of the male contact elements can be designed with a plug force of at most about 10 Newton for insertion into one of the holes. Thus, for example, in providing five contact elements to be simultaneously inserted into a printed circuit board by a user, a 50 Newton insertion force may be required, which a user can still easily apply.

The connection arrangement according to the invention can be used particularly advantageously for automotive applications, that is in motor vehicles of all kinds, combine harvesters, road construction machines, vehicle technology, railway technology, aviation technology, harvesting machinery or in other areas of off-road vehicles or agriculture. The high current capability of the connection arrangement may allow currents of 5 to 25 amperes and more per single pin of the contact elements to be made by applying a vibration load. Thus, the connection arrangement can be advantageously designed as an automotive connection arrangement. For example, according to the invention, a wire harness can be electrically coupled to a printed circuit board.

In the connection arrangement, the contact elements may be designed to be flexible at least in the regions to be arranged within the through-hole in a direction transverse to the insertion direction. In other words, upon insertion of the contact elements into the associated drill holes of the printed circuit board, a force can act on the contact elements forcing them into the contact holes. Thus, the contact elements can be under a slight bias when they dip into the contact hole. By this bias, a secure electrical contact with the mating contacts in the borehole interior can be made possible. At the same time, such contact forces, which are first to be overcome on the user side when inserting, should be small enough not to jeopardize the mechanical handling of a simultaneous insertion of several such contacts by a user, that is, the insertion forces should not be too large. Furthermore, the deflection characteristic of, for example, spring-like configured contact elements can be reversible, that is, when removing the plug element from the circuit board lead to an elastic springback. As a result, the plug-in element can be used several times and is not destroyed by a single use. A plastic deformation can be avoided by the compliant design of the contact elements and by the provision of the contact elements as two or more curved spring elements with a distance from each other.

Accordingly, it is preferred if the contact elements have two or more between them leaving a gap leg. Their outer sides facing away from each other can optionally be designed, for example, convexly curved. By such a curvature, an undesirable spreading of the legs in contact with a flat surface can be avoided. When using fork contacts an elastic pluggability can be achieved.

In the following, exemplary embodiments of the invention will be described with reference to the figures.

In the following, reference is made to 1 to 5 a connection arrangement 100 according to an exemplary embodiment of the. Invention described.

The connection arrangement 100 contains a printed circuit board 102 that has a plurality of contact element openings 104 having. Each of the contact element openings 104 is as a through hole formed in the example of plastic (FR4, impregnated with epoxy glass fiber mats) printed circuit board 102 executed, wherein the cylindrical inner wall of each of the contact element openings 104 is lined with an electrically conductive material to an electrically conductive connection to contact elements described in detail below 106 a direct plug arrangement according to the invention 108 to enable. On the circuit board 102 Further not shown interconnects and not shown electronic components are formed by means of the electrically conductive material and the contact elements 106 with a connected electronic component, such as a wiring harness, can be electrically coupled. Furthermore, the circuit board 102 four Vorjustieröffnungen arranged at corners of an imaginary rectangle 500 on that in 5 you can see.

The direct plug-in device 108 , which is described in more detail below, is used for direct plugging on the circuit board 102 by connecting four in 5 to be recognized Vorjustierzapfen 502 a plug element receptacle 112 the connection arrangement 108 with the Vorjustieröffnungen 500 for pre-adjusting and subsequent insertion of the contact elements 106 in the corresponding contact element openings 104 , First, the pre-adjustment ensures that the contact elements 106 in alignment with the corresponding contact element openings 104 be pre-positioned, so that only a depression of the direct plug-in device 108 on the circuit board 102 necessary to complete the electrical connection. The actual plugging process is thus only by the subsequent movement of the plug element 110 relative to that on the circuit board 102 pre-adjusted plug-in element receptacle 112 accomplished. By this relative movement, the contact elements 106 in the corresponding contact element openings 104 introduced while compressed side, namely one contact element 106 per contact element opening 104 ,

The direct plug-in device 108 is thus for direct plugging on the circuit board 102 intended. The direct plug-in device 108 contains the plug element 110 which is a recording case 114 and the plurality of plug-in spring-like contact elements received thereon or therein 106 having. How out 1 can be seen, each of the contact elements has a crimpable section 116 up with a in 1 not shown electrical conductor can be coupled, which can for example lead to a wiring harness. Electrically conductive connected to the crimpable section 116 are two fork-like spring-loaded contact element legs 118 mounted when inserted into an associated contact hole 104 the circuit board 102 be compressed and in the contact hole 104 introduced state an electrically conductive connection between the with the crimpable section 116 coupled electrical conductor and the contact in the contact holes 104 provides. The contact elements 106 are pluggable by hand and therefore very sensitive.

The plug element receptacle 112 , which may also be referred to as a skirt, is configured to be the male element 110 partially in their interior. Is the plug element 110 partly in the plug element receptacle 112 recorded, so are in recorded power-free state of the plug element 110 in the plug element receptacle 112 the contact elements 106 laterally, that is laterally, from the plug element receptacle 112 covered. The term "lateral" in this context should be understood to mean that along a part or the entire outer circumferential surface of the plug element receptacle 112 the contact elements 106 are not exposed to the outside, but instead of the contact element recording 112 covered or enclosed.

1 shows the direct plug-in device 108 now in a state in which the contact elements 106 not yet in the contact openings 104 the circuit board 102 are inserted, but in which a circuit board side underside of the plug element receptacle 112 on a main surface of the circuit board 102 just hung up. More specifically, the plug element receptacle 112 so on the circuit board 102 put on the pre-adjustment pins 502 at the bottom of the plug element receptacle 112 in the corresponding arranged Vorjustieröffnungen 500 the circuit board 102 are introduced. This is a correct pre-adjustment of the direct plug-in device 108 relative to the circuit board 102 ensured.

To now the contact elements 106 in the contact opening 104 to sink and thus the electrically conductive contact between the circuit board 102 and the contact elements 106 to accomplish, the plug-in element 110 starting from the in 1 shown operating state relative to the plug element receptacle 112 in the in 2 shown operating state by a user in the in 2 with one direction a compressive force on the plug element 110 exercises. As a result, the plug element shifts 110 relative to the plug element receptacle 112 , whereby the contact elements 106 through the contact holes 104 be performed. Due to the pre-adjustment previously carried out, the contact elements are aligned directly before insertion 106 already with the associated contact holes 104 ,

As in 1 shown, surmounted in the plug element receptacle 112 recorded state of the plug element 108 and before the insertion movement, the plug element receptacle 112 the contact elements 106 on the circuit board side by a distance D.
